The chloride ion content in cement was mensurated by ammonium theiocyanate volumetric method, and the uncertainty was evaluated. And mathematical model was established to analyse quantitively several parameters as measurement repeatability of uncer-tainty components, standard titration solution volume consumption and sample mass etc, the combined uncertainty was calculated and method to reduce uncertainty in experiment was put forward.
